Methods of managing audio data transmissions over a network disclosed herein may include the step of selecting a client device from a plurality of client devices as a participating device, each client device of the plurality of client devices being in data communication with a network. The methods may include the step of signaling the participating device over said network thereby initiating transmitting of audio data from the participating device at least in part over said network for live broadcasting, the audio data being indicative of a speaking voice being input into a participating device microphone of the participating device. The methods may include the step of minimizing latency in transmitting of the audio data by throttling data being communicated over said network by one or more client devices of the plurality of client devices only while the participating device is transmitting audio data over said network.

Various example implementations are directed to circuits, apparatuses, and methods for providing virtual computing services. One example involves a data storage device and a set of computing servers communicatively coupled to the data storage device. The set of computer servers provide a respective virtual data center for each of a plurality of accounts, and the respective virtual data center for each account provides virtual services specified in a respective settings file for the account stored in the data storage device. The virtual data center for at least one of the accounts includes a set of virtual desktops and a set virtual servers, including at least one Voice-over-IP (VoIP) server. The VOIP server provides VOIP service for a plurality of users of the account.

According to an aspect, there is provided a method performed by a communication network for negotiating a data transfer between an application service and a user equipment, UE, via the communication network. The method comprises receiving, from the application service or a negotiation function associated with the application service, a request for data transfer, wherein the request includes an indication of an amount of data to be transferred and one or more of the following: one or more service constraints associated with the data transfer, and a trajectory of the UE; obtaining predicted capacity for network resources needed to execute the data transfer according to the information included with the request; based on the predicted capacity, determining whether the request can be fulfilled according to the information included with the request; and sending a response to the request based on the result of the determination.

Systems and methods relating to selection of user plane functions in a core network and a radio access network of a cellular communications network that take into consideration information related to application server selection are disclosed. In some embodiments, a method of operation of a network node in a cellular communications network that comprises a radio access network and a core network comprises selecting a user plane function for a protocol data unit session for a wireless device based on information related to application server selection such that the protocol data unit session for the wireless device utilizes the selected user plane function. In this manner, optimal user plane connectivity between an application client in the wireless device and an application server is provided.

A method for managing network slice enabled traffic on a communications network is disclosed. The network slice is instantiated on the communications network for providing connectivity resources to a network operator using the communications network. The method comprises measuring a traffic level indicative of the traffic enabled by the network slice; and adjusting the traffic enabled by the network slice in accordance with the traffic level and a network operator enabled function associated with the network slice.

Optimizing performance between a wireless distribution system (WDS) and a macro network(s). In this regard, a macro network optimization system is configured to detect a performance indicator(s) between a WDS and a macro network and optimize the performance of the macro network based on the detected performance indicator(s). The macro network optimization system analyzes a macro network performance report provided by the macro network and/or a WDS performance report provided by the WDS to detect the performance indicator(s) between the WDS and the macro network. The macro network optimization system reconfigures operations of one or more macro network elements to optimize performance between the WDS and the macro network based on the detected performance indicator(s). By detecting and optimizing performance between the WDS and the macro network, capacity, throughput, and/or coverage of the WDS and the macro network can be improved, thus providing better quality of experience (QoE).

An intermediate node (203) for a transport network (200) is configured such that traffic flows between at least one remote access node (201) and a central hub node (202) pass via the intermediate node (203). The intermediate node (203) is configured to selectively process a traffic flow depending on a responsiveness requirement of the traffic flow.

Preference information is received at a network repository function from a first network function, the preference information indicating one or more optional preferences for a respective second network function or network function service. Information is provided to the first network function about one or more second network functions or network function services, the one or more second network functions or network function services being selected taking into account the preference information.

A method and system for providing access to Quality of Service levels from within a network to entities outside of the network.
